Why my Growatt SPF 3000T HVM-G2 Inverter has no response after power on?
If your Growatt Inverter shows no response after powering on, it might be due to: * The battery voltage being far too low: Check the battery and wiring connections, recharge the battery, or replace the battery. * Reversed battery polarity: Check the battery and wiring connections, recharge the battery, or replace the battery.
How to fix Growatt SPF 3000T HVM-G2 that shuts down during startup?
If your Growatt Inverter unit shuts down automatically during startup, it's likely because the battery voltage is too low (less than 1.91V/Cell). To resolve this, try to recharge the battery or replace it.
